If you're looking for a new streaming music service that's packed with remixes, music that's easy to discover, and a music stream that's tailored to your interests, consider the freshly launched 2u.fm. The service has plenty of social elements if you want to invite and follow friends, but it's really a well-organized, good-looking streaming service that's completely and totally free.

As soon as you sign up, 2u.fm asks you to select some genres that you enjoy, follow some artists who's music you love, and—if you choose—invite some friends. You can sign up with Facebook (or not, if you'd rather sign up via email) to find friends that way, or you can get right to listening. Your feed shows music the service thinks you'll love, the Trending section shows songs that other users have most liked today, and you can follow friends, stations created by others, or just browse genres for something to listen to. Hover over song names, artist names, and more to see even more tags you can use to filter and organize your feed. You can read more of the service's features here.

Behind the scenes, the layout and design supports mobile devices, so the webapp works just as well on your iPad or Nexus 7 as it does in your browser. You can share any song you find on the service with friends, and if one of your friends is online, you can tune in to what they're listening to in real time and rock out with them. The service is brand new and a side-project for its developer, so there are still a few kinks to work out (and no, it doesn't have a sprawling million-track music library. The service is about discovering new music, not finding songs you've heard), but it's completely free, ad-free, and off to a great start.
